Well, you need some links to start with. And they need to target the IFRAME.

For the scrolling you could use JavaScript (scrollTo(), scrollBy()). It may or not work well since you are bound to use pixels. It's probably better to add an id to the iframe and then just let JavaScript change the location to that anchor.

I always forget about scrollIntoView(). Thanks for the reminder. Ppk says there are some problems with it on iPhone, but that could very well be remedied by now. I don't think it does anything that just changing the location to an anchor wouldn't. ppk doesn't seem to think so either.http://www.quirksmode.org/dom/w3c_cssom.html
